What is the seated zottman curl?
Named after 19th-century strongman George Zottman, this curl combines a supinated curl up with a pronated lower. Sitting on a bench keeps the back out of it. You curl the dumbbells with palms up, rotate at the top so palms face down, then lower slowly under that pronated load. You hit the biceps in their strongest position and the brachialis and forearms in their hardest position.
How to do the seated zottman curl
- 1
Sit tall and set the grip
Bench at ninety degrees, feet planted. Dumbbells in hand, palms facing forward (supinated).
- 2
Curl up supinated
Drive the bells up by squeezing the biceps. Keep the elbows pinned to the ribs, no swing.
- 3
Rotate at the top
At the peak of the curl, rotate the wrists until your palms face down. This is the Zottman flip.
- 4
Lower pronated, slow
Take three to four seconds to lower the dumbbells with palms down. At the bottom, flip back to supinated and repeat.
Pro tip
Half the people doing Zottman curls go too heavy and skip the slow eccentric. The forearm work only happens if you take four seconds down. Load light, lower slow.
Common mistakes
Swinging the dumbbells.
Body English cheats both halves of the rep. Strict elbows, hips on the bench.
Flipping too early.
Rotate at the very top, when the biceps are fully shortened. Mid-curl rotation kills the load.
Dropping the eccentric.
Pronated lowering is where the brachialis grows. If you can't slow it down, halve the weight.
Going too heavy.
Forearm strength caps the lift before bicep strength does. Use about seventy percent of your strict curl weight.
Variations and progressions
Easier
Alternating Zottman
Curl one arm at a time. The other side rests, you get longer time under tension per arm.
Harder
Standing Zottman + tempo
Standing adds a stability demand. Add a 5-second pronated lower for a forearm finisher that bites.
Want pure biceps?
Hammer curl + reverse curl
Two separate exercises do the same job as one Zottman. Pick this if you train arms more than twice a week.
How to program it
Three protocols by goal. Pick one per cycle and aim for progression on load or distance.
| Goal | Sets × distance | Load | Rest |
|---|---|---|---|
| Strength | 4 × 6-8 reps | 12-16 kg / hand | 90 s |
| Hypertrophy | 3 × 10-12 reps with 3 s pronated lower | 8-12 kg / hand | 60 s |
| Forearm finisher | 2 × 15 reps slow | 5-8 kg / hand | 45 s |
Seated Zottman Curl FAQ
Why not just do a hammer curl?
A hammer curl trains the brachialis with a neutral grip, but never loads pronated. The Zottman adds that pronated eccentric, which is what builds the brachioradialis and grip-side forearm. One exercise covers what otherwise takes two, with the bonus of training the biceps in their strongest position.
Will it really help my grip?
Yes, especially the wrist extensors that most curls ignore. After four to six weeks of weekly Zottmans, deadlift grip and hangboard endurance both tend to improve. It won't replace dedicated grip work like farmer carries or a fat-bar hold, but it's a strong base-builder.
How does it fit with regular bicep curls?
Treat it as a finisher after your main curl variation. Three or four sets of supinated curls heavy, then two or three sets of Zottmans light and slow. The Zottman adds time under tension and forearm work without adding much fatigue to the biceps themselves.
